Abstract: A shock absorbing liner to be attached to the interior of a baseball shoe to help protect the toes and upper portion of wearer's foot from injury that can occur during baseball batting. The shock absorbing liner includes a plurality of rigid protective shell members constructed of a hard plastic material that possess sufficient shock absorbing capability to resist a wide range of dynamic impact forces that may be applied to the baseball shoe by a foul tipped ball striking the shoe. The rigid protective shell members are shaped and arranged to cover and protect essentially the entire upper foot region including the toes. The rigid protective shell members are joined by bendable elements so as to allow the shock absorbing liner freedom to flex with the baseball shoe while affording foot protection.
